The Analytical Distillation of Petroleum

Abstract

THE JOURNAL OF INDUSTRIAL AND ENGINEERING CHEMISTRY oils of Borneo, Sumatra and Java are relatively rich in light aromatic compounds, but low in nitrogen. The latter oils, however, are very light and fluid and very different from the heavy pitch-like oils of California and Mexico, and it has been frequently suggested that these light fluid oils have been purified by filtration through porous strata. Such light, supposedly filtered, crudes are low in sulfur as well as Fig. V-Fractional Distillation of Gasoline Made by Cracking under 100 Lbs. Pressure nitrogen. Thus the converse of the above statement does not hold, probably for the reasons just indicated.Another noteworthy feature of gasoline made by cracking under a pressure of 100 lbs. is that normal paraffine hydrocarbons appear to be the predominating constituents. The amount of isopentane exceeds that of normal pentane but the hexane and heptane fractions appear to consist chiefly of the normal paraffines. These facts are brought out by Fig. V, repre-
